GRAND RAPIDS, Mich. — At first, Dominic Turgeon didn’t think much of the lingering pain in his right arm, assuming it was a weird, nagging bruise.

But after the Grand Rapids Griffins’ practice on April 10 in San Antonio, where the team was skating in advance of the next day’s game against the Rampage, teammate Matt Puempel remarked on how swollen it was. Puempel had done some cursory reading about blood clots after his former New York Rangers teammate Chris Kreider suffered one in January and remembered that was a warning sign.

Turgeon told the team’s athletic trainer what he was experiencing and within an hour of arriving at St. David’s Round Rock Medical Center in Round Rock, Texas, he was undergoing emergency surgery to remove a blood clot in his arm.

Most of the Griffins didn’t find out until the afternoon of the game. An announcement was made by the coaching staff on the bus ride to the arena.
